In routine air conduction testing, what is the first frequency to be tested?

In routine air conduction testing, the first frequency typically tested is 1000 Hz. This frequency is chosen because it is within the range of most common speech sounds and is considered a mid-range frequency where many individuals have optimal hearing sensitivity. Testing begins at 1000 Hz as it provides a reliable indication of a person's hearing ability, and deviations from normal thresholds can be more easily identified at this frequency.

Additionally, starting the test at 1000 Hz allows audiologists to establish a baseline before moving to lower and higher frequencies, such as 500 Hz or 2000 Hz, where hearing loss might also be present. The selection of this frequency is standardized in audiological practices to ensure consistency and reliability in hearing assessments.
